The following describes a method, an electronic device, and a storage medium for replacing a start page at compile time according to the present invention with reference to fig. 2.
The invention provides a method for replacing a starting page during compiling, which can effectively avoid the intrusiveness of codes and reduce the coupling.
The invention provides a method for replacing a starting page during compiling, which comprises the following steps in an Android language:
s1, during coding, a developer adds a specified annotation to a class of a C page to be replaced in an extension module, wherein the annotation contains information of a replaced page and a replaced page (the annotation can be a self-defined annotation, and only needs to be the same annotation as the annotation during instrumentation).
And S2, inserting intermediate copy information into the replaced B page in the original module during compiling, wherein the type of the intermediate copy information is the class information of the replaced B page, the intermediate copy information needs to be used when the page is started, and the intermediate copy information contains information such as the full class name of the class information of the replaced B page.
And S3, during compilation, scanning all places calling the attribute of the replaced B page class information, and replacing the class information instruction calling the replaced B page with an instruction calling intermediate copy information of the replaced B page.
S4, during compiling, scanning the annotation added in the step one through a compiler, acquiring the replacement information contained in the annotation, and storing the replacement information.
And S5, during compiling, inserting a replacement code at the starting position of the App, and assigning the class information of the page C to be replaced to the intermediate copy information of the page B to be replaced.
When App is started, the replacement code inserted in S5 is preferentially executed, the class information of the page C to be replaced is given to the intermediate copy information of the page B to be replaced, and when the logic of the page B to be replaced of the starting page is executed, the class information of the page B to be replaced is already replaced by the intermediate copy information in step S3 during the compiling period, so that the information of the page C to be replaced when the starting information is read by the system, the purpose of replacing the starting page is achieved, and the implicit code calling is completed.
The annotation in this example is some meta-information attached to the code for compiling and runtime parsing and use, and functions of explanation and configuration. The annotation does not affect the actual logic of the code and only serves an ancillary role.
The ASM framework in this example is a Java class information handling framework. It can modify existing classes in binary form or dynamically generate classes. The ASM can either directly generate the binary class file or dynamically change the class behavior before the class is loaded into the Java virtual machine. After the ASM reads information from the class file, the ASM can change class behaviors, analyze class information and even generate a new class according to user requirements. And S2, S3, and S5, pile inserting is carried out on the original module through the ASM frame. Instrumentation is the addition, modification, or deletion of binary code instructions.
In this example, the class information is a binary file containing the execution program, consisting of a sequence of op code/data pairs, which is a type of intermediate code.
When the App is started, the replacement code inserted in the step S5 is preferentially executed, the type information of the page to be replaced is given to the self-defined attribute of the replaced page, and when the logic of the replaced page is started, the type information of the replaced page is replaced by the inserted self-defined attribute in the step S3, so that the information of the page to be replaced is read by the system when the information is started.
The method has no invasion to the original code, dynamically supports the expansion module, does not refer and modify, and has no influence on the original logic.
Fig. 3 illustrates a physical structure diagram of an electronic device, which may include, as shown in fig. 3: a processor (processor) 810, a communication Interface 820, a memory 830 and a communication bus 840, wherein the processor 810, the communication Interface 820 and the memory 830 communicate with each other via the communication bus 840. The processor 810 may call logic instructions in the memory 830 to perform a method of replacing a launch page at compile time.
In addition, the logic instructions in the memory 830 may be implemented in software functional units and stored in a computer readable storage medium when the logic instructions are sold or used as independent products. Based on such understanding, the technical solution of the present invention may be embodied in the form of a software product, which is stored in a storage medium and includes instructions for causing a computer device (which may be a personal computer, a server, or a network device) to execute all or part of the steps of the method according to the embodiments of the present invention. And the aforementioned storage medium includes: a U-disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk, or an optical disk, and various media capable of storing program codes.
In yet another aspect, the present invention also provides a non-transitory computer readable storage medium having stored thereon a computer program which, when executed by a processor, is implemented to perform the above-provided method of replacing a launch-on page at compile time.
The above-described embodiments of the apparatus are merely illustrative, and the units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.
Through the above description of the embodiments, those skilled in the art will clearly understand that each embodiment can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware. Based on the understanding, the above technical solutions substantially or otherwise contributing to the prior art may be embodied in the form of a software product, which may be stored in a computer-readable storage medium, such as ROM/RAM, magnetic disk, optical disk, etc., and includes several instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to execute the method according to the various embodiments or some parts of the embodiments.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
